A millimetre-wave Gunn triode device using an AlGaAs/GaAs quantum well structure is realised. The material used was grown by molecular beam epitaxy and devices were made using electron beam lithography Oscillation occurs at 83 GHz for a 0.5 mu m gate length device with a 1.3 mu m gate-cathode separation. Experimental results are in excellent agreement with Monte Carlo calculations. Planar Gunn triodes have potential for high frequency chip integration for millimetre-wave and terahertz applications.
